In this document you will find warnings and cautions for installation, use and maintenance of the pumps.

Here’s the meaning of symbols you may find in this document and general warnings that you should keep in mind.

WARNING: This symbol aware that there is a danger of serious bodily injury or death if you ignore the warning described.

CAUTION: This symbol aware that there is a danger of personal injury or property damage if you ignore the caution described.

• This equipment is for professional use only.

• Do not degrade the integrity of the equipment. Use only original

replacement components from Samoa Industrial, S.A.

• Fluids not suitable for the pump can cause damage to the pump unit

and involve risk of serious personal injury. Always consult Samoa

Industrial, S.A. if you have any questions about the compatibility within

the fluids and the pump materials, including elastomers.

• Install and use the pump according to all local and national regulations

and abide all health and safety laws or legislation.

• The pump can produce fluid pressures equal to the air supply pressure.

Do not exceed the maximum allowable pressure of 120 psi (8 bar) air

supply. The total hydraulic pressure (differential pressure + system)

should never exceed 120 psi (8 bar).

• Never use a pump that leaks, that is damaged, that is corroded or

otherwise it may lack the capacity to contain the fluid.

• Frequently check that the bolts on the diaphragm cover of the pump

are torqued correctly.

• Do not use a model with aluminium wetted surfaces to pump fluids for

human consumption, there is a possibility of trace contamination of lead.

• Danger of explosion if used 1,1,1-trichloroethane, methylene chloride

or other halogenated hydrocarbon solvents with aluminium wetted

materials. It could cause serious injury and property damage.

• Inside the pump, diaphragms separate the fluid that is being pumped

from the air supply. If a diaphragm breaks, the fluid can leak out of the

air exhaust and contaminate the environment.

• When handling hazardous fluids, always route the air exhaust into a

suitable container and locate it in a safe place. (Optional conection

system at customer’s request. Not supplied with the unit).

• When the fluid source level is situated higher than the pump, (flooded

suction), the outlet tank must be at a higher level than the product to

prevent spills.

• For pumps handling hazardous fluids that are a danger to humans or

to the environment, install a suitable container surrounding the pump

to prevent any leaks or spills.

• Ensure that the operators of this equipment are trained on the

operation and limitations. Use safety equipment as safety goggles or

other equipment required.

WARNING: CAREFULLY READ THE INSTRUCTIONS AND WARNINGS BEFORE OPERATING THE EQUIPMENT!

WARNINGS AND CAUTIONS

Air operated double diaphragm pumps are air-powered, reciprocating

positive displacement pumps with two pumping chambers. Two

diaphragms, centrally located in the chambers, separate the compressed

air (dry side) from the fluid being pumped (wet side). A shaft transmits

the reciprocating motion of one diaphragm to the other. A directional

valve alternatively distributes the air from one chamber to the other; thus

a reciprocating movement of the diaphragms is created. With each

stroke, fluid is discharged by one of the diaphragms whilst the opposite

diaphragm sucks new fluid into the expanding chamber. Check valves,

two on the discharge side and two on the suction side, control and direct

the fluid flow.

DESCRIPTION

• Remove the pump from its package and install it on the chosen location.

• Try to minimize the suction head. Install the pump as close as possible to the fluid being pumped.

• Remember to have enough space around the pump to perform maintenance tasks.

• Keep in mind to connect the inlet and outlet of the pump correctly.

• In case of diaphragm pump failure, the air exhaust will expel the product being pumped.

• When the pump is installed in a place where a spill of fluid can cause an environmental impact, the exhaust should be directed to a place.where

this spill could be contained.

• When installing the pump in its place, use brackets to secure its base.

• Fasten all bolts with the torques contained in this manual.

FLOODED:

The pumping system was designed with positive pressure at the inlet.

This is the best possible installation when you need to evacuate the liquid

from the drum or tank, or when working with viscous fluids.

Not recommended for hazardous fluids.

SELF-PRIMING:

Pump is designed to generate vacuum. It is possible to evacuate all the air

from a hose or pipe without damaging the pump. Maximum suction

height is (5 m) 16.5 ft, with the suction hose empty and up to 8 m (26.25

ft) with the hose primed.

NOTE: Use a pressure regulator with

built-in filter inlet.

NOTE: The compressed air supply must

be between 1,5 bar (20 psi) and

8 bar (120 psi).

THIS PUMP IS SELF-PRIMING

To prime it the first time, you must connect the air pump supply to a low pressure using the pressure regulators while keeping the outlet valve open.

When fluid begins to flow from the pump outlet, the pump is primed. For regulation of fluid pressure, the unit must be supplied with an air pressure

between 1,5 and 8 bar (20 and 120 psi). Adjust the discharge valve on the discharge side to control flow. For the performance characteristics of the

pump see the capacity curve.

• Stop the air supply.

• Make sure for your safety that the air valve is closed.

• Close the discharge valve and the suction valve. Open inlet and outlet drain valves.

• Open the air valve of the pump, running bring on the pump and flushing the remaining fluid.

• Close the air valve.

• After ensuring that the pump was turned off and the pressure was released, pump is ready for its maintenance.

WARNING

Connect grounding wires to the pump, piping and all other

equipment too.

When the pump operates ungrounded or with an incorrect

connection, friction between parts and abrasion caused by some

fluids that flow inside the pump, can generate static electricity.

Moreover, according to the type of fluid pump and the

installation environment (such as gases in the air or the type of

the surrounding facilities) static electricity can cause fire or

electric shock.

When installing the pump, be sure to perform grounding in the specified

location.

Also connect ground wires for the auxiliary equipment and piping.

Use a grounding cable of at least 12 gauge (2.0 mm2).

If the pump you have purchased is valid for Atex, a specific Atex manual

will accompany this one. Read this manual before operating the pump.

If the unit is marked with the symbol , it can be used in potentially

explosive atmospheres. Below this symbol, in the nameplate of the pump,

are indicated the areas for which the equipment is approved. You will also

find the maximum allowable surface temperature in the same plate.

alguna duda sobre la compatibilidad de los fluidos con los materiales

de la bomba, incluyendo los elastómeros.

• Instale y use siempre la bomba según la normativa y la legislación

sanitaria y de seguridad, tanto local como nacional.

• La bomba puede producir presiones de fluido iguales a la presión de

alimentación del aire. No exceder la presión máxima permitida de

alimentación de aire de 8 bar (120 psi). La presión hidráulica total

(presión del sistema + presión diferencial) no deberá exceder nunca 8 bar

(120 psi).

• No utilice nunca una bomba que tenga fugas o daños, esté corroída o

de otra forma carezca de la capacidad para contener el fluido interno

o la presión del aire.

• Comprobar con frecuencia que los tornillos de las tapas de la bomba

están correctamente apretados.

• No use modelos cuya parte húmeda esté basada en aluminio para

bombear productos de consumo humano, es posible que existan trazas

de plomo.

• Peligro de explosión si se usa 1,1,1-tricloroetano, cloruro de metileno

u otros disolventes de hidrocarburos halogenados en sistemas de fluido

a presión que tengan componentes de aluminio en la parte de fluido.

Podría causar graves daños materiales y personales incluso mortales.

• En el interior de la bomba, dos membranas separan el fluido bombeado

de la alimentación de aire. Si se rompe una membrana, el fluido puede

salir proyectado por el orificio de evacuación de aire.

• Cuando se manejen fluidos peligrosos, conecte siempre el orificio de

evacuación de aire a un recipiente adecuado y situado en un lugar

seguro. (Sistema de conexión opcional a petición del cliente. No se

suministra con el equipo).

• Cuando la fuente de producto se encuentre a un nivel más elevado que

la bomba (aspiración inundada), la impulsión deberá ser dirigida por

un tubo a un nivel más alto que el producto para impedir los derrames

causados por derivación sifónica.

• En las bombas que manejen fluidos peligrosos para las personas o el

medio ambiente, se debe instalar algún tipo de recipiente o contenedor

para recoger posibles fugas y evitar su derrame.

• Asegúrese de que el operario de este equipo esté formado en cuanto a

la operación, limitaciones y uso de equipamiento de seguridad como

gafas de seguridad u otro equipamiento requerido.

ADVERTENCIA: ¡Lea atentamente el manual de instrucciones y sus advertencias antes de empezar a operar con el equipo!

La bomba de membrana neumática es una bomba aspirante e impelente

de desplazamiento positivo, accionada por aire y con dos cámaras de

bombeo. Dos membranas ubicadas centralmente en las cámaras, separan

el aire comprimido (lado seco) del fluido bombeado (lado húmedo). Las

membranas están conectadas entre sí mediante un eje flotante cuyo

funcionamiento permite la minimización del flujo pulsante. Una válvula

(motor neumático) distribuye el aire de una cámara a la otra

alternativamente, produciendo así un movimiento recíproco de las

membranas.

En cada embolada, una de las membranas desplaza el fluido, mientras

que la membrana opuesta aspira nuevo fluido al interior de la cámara de

expansión. Cuatro válvulas de bola, dos en el lado de aspiración y dos en

el lado de impulsión, controlan y dirigen el flujo del fluido.

INUNDADA

El sistema de bombeo se diseñó para presión positiva en la aspiración.

Esta es la mejor forma de instalación cuando se necesite evacuar todo el

líquido del bidón o depósito, o cuando se trabaje con fluidos viscosos. No

recomendada para fluidos peligrosos.

ASPIRACIÓN:

La bomba DP está diseñada para generar vacío en la aspiración. Es posible

evacuar todo el aire de una manguera o tubería sin dañar la bomba. La

altura máxima de succión es de 5 m con la manguera de succión vacía y

hasta 8 m con la manguera cebada.

NOTA: Utilice un regulador de presión con

filtro incorporado en la entrada de aire.

NOTA: La presión de alimentación de aire

debe estar comprendida entre 1,5 bar (20

psi) y 8 bar (120 psi).

ASPIRACIÓN SUMERGIDA

INUNDADA

SUMERGIDO:

Todas las bombas DP se pueden sumergir en los fluidos. Es importante

que verifique que todos los componentes que están en contacto con el

fluido son químicamente compatibles. En este caso, las salidas de aire y

fluido deben ser conducidas al exterior mediante mangueras. (Sistema de

conexión de aire opcional).

LAS BOMBAS DP SON MUY FLEXIBLES Y FÁCILES DE INSTALAR INUNDADA

INSTALACIÓN RECOMENDADA

Nota: Para el empleo de la salida de fluido

superior, retire el tapón y emplee una manguera

con la conexión adecuada para las roscas de

la bomba.

Use el tapón retirado para cerrar la salida

convencional. Recuerde usar cinta de teflón para

ADVERTENCIA

Para que el suministro de aire sea suficiente para satisfacer la demanda de la bomba, el diámetro de la tubería debe ser igual al diámetro del

orificio de suministro de la bomba. También elija equipos auxiliares y materiales con suficiente flujo de aire para el consumo de aire de la bomba.

También considere el uso y la estabilidad de la presión de aire. Además, el equipo periférico debe estar instalado lo más cerca posible de la

unidad de la bomba.

El uso de un acoplador para conectar cada manguera facilita la operación y las tareas de mantenimiento.

ESTA BOMBA ES AUTO-CEBANTE.

Para cebarla la primera vez, es conveniente conectar el aire a la bomba a baja presión con el regulador de presión, manteniendo la válvula de salida abierta.

Cuando el fluido empieza a salir, la bomba está cebada. Para su regulación mediante presión de fluido se debe alimentar con presión de aire

comprendida entre 1,5 y 8 bar (20 - 120 psi). Ajuste la válvula de impulsión en el lado de descarga. Para la relación entre el flujo, la presión de

suministro de aire y la presión de descarga, vea la curva de capacidad.

• Corte el suministro de aire.

• Compruebe por su seguridad que la válvula de aire de la bomba esté cerrada.

• Cierre las válvulas de aspiración y descarga. Abra las válvulas de drenaje (aspiración e impulsión).

• Abra la válvula de aire de la bomba, ponga en funcionamiento la bomba y descargue el fluido remanente.

• Cierre la válvula de aire.

• Asegúrese de que la bomba se ha detenido y no existe presión en las líneas de fluido. La bomba está lista para el mantenimiento.

ADVERTENCIA:

Asegúrese de conectar conductores a tierra para la bomba,

tuberías y otros equipos conectados.

Cuando la bomba opera sin conexión a tierra o con una conexión

incorrecta, la fricción entre las piezas y la abrasión causada por

algunos fluidos que fluyen dentro de la bomba pueden generar

electricidad estática. Además, según el tipo de fluido a bombear

y el ambiente de la instalación (como gases en el aire o el tipo de

las instalaciones circundantes) la electricidad estática puede ser

causa de incendio o choque eléctrico.

• Cuando instale la bomba, asegúrese de realizar la conexión a tierra en

el lugar especificado.

• Conecte también conductores a tierra para los equipos auxiliares y las

tuberías.

• Utilice un cable con conexión a tierra de por lo menos 2,0 mm2.

• Si la bomba que ha adquirido es válida para Atex, a este manual lo

acompañará uno específico para Atex. Lea este manual antes de operar

con la bomba.

• Si la bomba viene marcada con el símbolo , esta puede ser usada

en atmósferas potencialmente explosivas. Debajo de este símbolo, en

las placa de identificación de la bomba, vienen indicadas las zonas para

las que el equipo está aprobado. Encontrará también la temperatura de

superficie máxima permitida en la placa de su bomba.
